Assembly Of The Rail Brackets; Setting Connection Rail; Stop Ends; Setting The Intermediary Entry - Exit - Tractel travrail Manual De Instalación, Utilización Y Mantenimiento

Fixing brackets on its structural supports shall be done
by stainless steel screws M12 with an ultimate shear
stress of 20000 N.
GB
In case of bolting on steel or wood, it shall be necessary
that a skilled technician verifies by calculation that the
data for design and assembly are compliant with norm
EN 795-D 2012 and TS 16415:2013.
• For concrete or stone, it is obligatory to bolt the
brackets by chemical anchors or crossing rods. It is
then necessary to check the anchorage quality by a
test of 5000 N for 15 seconds. This test shall be made
before the installation of the travrail components.
Performing this check with the rail components would
distort the anchoring.
• For wood, it is mandatory to bolt the brackets by
crossing rods or counter-plate.
• For bolting on any other material, it is necessary that
the installer checks the compliance of the structural
material either by calculation or a test.
If specific interfaces have to be used, the installer shall
take care that they are designed and manufactured by
a skilled person. Those interfaces shall be efficiently
treated against corrosion.
A sign plate shall indicate anchoring presence in a
secure area near the anchoring or the area access.
This sign plate shall be filled after the assembly and
after each periodic review. This sign plate shall act as
well as an ID form.
Two brackets at least, whatever the length is. Refer to
section 7.2
Space between bracket of 6 m maximum.
A bracket before and after an angle.
Cantilever of the rail of 200 mm maximum.
Installation of the supports to be bolted with screws M12 in
stainless steel.
For suspended works, the space between bracket must not
exceed 3 m.
The bolts tightening shall be done with a dynamometric
wrench according the table below:

6.2. Assembly of the rail brackets

Rail brackets shall be put every 6 m maximum,
whatever is the position of the connection rail. Brackets
shall be set on structural support that can withstand the
installation of a fall arrest device type D (14000 N in fall
direction for 3 persons for each bracket).
1. Set rail bracket with a stainless steel screw M12
of an adequate length (bolting shall have an anti-
loosening device.
2. Torque the screw.
3. Open the bracket part with the help of a 6 mm hex
wrench (see Fig. 12).
4. For great lengths submitted to thermic expansion, it is
possible to set specific expansion brackets that would
unlock the longitudinal moving of the rail (see Fig. 13).
To avoid the screw loosening, screws M8 shall be set
with Loctite 243.

6.3. Setting c
Connection rail can be set by fitting them into the rail
and fixing with two countersunk head socket screws
M8. To avoid any loosening, put Loctite 243 or similar
product (see Fig. 14).
NOTE: A marking can be made with a pen on
the screw to ease next checks.

6.4. Stop ends

The stop ends can be set by fitting it into the rail and
fixing with two countersunk head socket screws M8. To
avoid any loosening, put Loctite 243 or similar product
(see Fig. 15).
IMPORTANT: Any cantilever must be shorter than
200 mm (see Fig. 16).

6.5. Setting the intermediary entry - exit

The intermediary entry – exit is set with two fixings M12
separated 164 mm.
Brackets must be put on both sides of this part at a
distance of 1 m maximum following the schema above
(see Fig. 17).
Provide Loctite 243 to avoid the loosening of the four
countersunk head socket screws M8.

6.6. Machining the rail

Rail can be cut, taking care that the cut section is
perpendicular to the rail longitudinal axis. After a cutting
operation, the section edges shall be deburred properly.
